Air Quality Monitoring

As an effective solution for indoor gas environment monitoring, air quality monitoring devices have gained widespread adoption in recent years due to their advantages, including portability, ease of operation, and real-time monitoring capabilities. However, most conventional indoor air quality monitors currently available have relatively limited functionality, typically measuring only a single environmental parameter and lacking a comprehensive assessment of indoor air quality. Furthermore, many indoor gas detection devices do not perform further analysis or processing of the detected gas parameters, overlooking the cross-sensitivity commonly found in gas sensors. As a result, measurement results can be easily affected by interfering gases, making it difficult to achieve high detection accuracy.
